Pinned topic What's the problem when it shows "Oplrun process did not response, you must restart the running configuration"?

‏2013-12-04T11:20:23Z |

During the run time of a CP model, it shows "Oplrun process did not response, you must restart the running configuration", and then the model is stopped running. What's wrong with it?

Thank you for your help.

Heidi

    Hi,

    maybe you ran out of memory.

    Have you tried to run your model with oplrun ?

     

    regards

    Hi, Alex,

    I  ran the same instance, sometimes it was good, sometimes it ran into such problem. I don't know why.

    Thank you.

    Hi Heidi,

    To narrow down he problem, I 'd like to have more information on you setup:

    What version of OPL are you using?

    Are you on a multi core machine?

    Are you sharing the machine with other users (or running other processes that may consume system resources) ?

    Cheers,

    Hi rdumeur,

    I was using CPLEX 12.5. I was on a multi core machine, and the machine was used only by myself.

    Thanks.

    Dear Heidi,

    First, if possible, I would suggest to upgrade to the latest version of OPL. Each release fixes bug and maybe you did hit one.

    Another possibility is that your model was very large and your computer had not enough RAM to process it.

    Any indication on your model is welcome (e.g. the start banner displayed in the engine log window).

    Cheers,

    Probably not the same issue, but I've faced similar error message before. In my case it happened every time I tried to run any model (from either COS or ODME run configurations). The only way I found out to solve that was resetting my eclipse workspace.

    I still haven't been able to determine when the workspace corruption took place, but it happened three times in the last two months.

    Hi rdumeur

    I've faced similar error and I know that's because of lacking memory.I read in cplex manual that we could set nodefileind parameter to use disk space instead of RAM.But I've no idea that it works for CP. could you inform me if it works?
